Our lab work is to understand the code of an open source module and make any necessary changes to them. For this purpose, we use a Linux operating system installed on a Virtual Machine. We carry out all subsequent lab work in this software environment.

Prerequisite Knowledge

Familiarity with Virtual Environments such as VMware or Virtual Box and Linux Operating System

Background:

Virtual Machine:
A virtual machine (VM) is a software-based emulation of a computer system. It is comprised of a set of specification and configuration files and is backed by the physical resources of a host. One important use of a VM (also known as guest) is to run another operating system that is not native on your hardware. The end user has the same experience as they would have on dedicated hardware.
In this lab we will be using VirtualBox virtual machine.

Directions:

1. Installing VirtualBox: To begin your installation process, go to https://www.virtualbox.org/wiki/Downloads and download the respective binary file native to your host operating system.2. Once you have the binary downloaded, execute the file and follow the instructions to install.• For Mac OS X hosts, double-click on the file and follow instructions. This will create a VirtualBox icon in your Applications folder.• For Window hosts, double-click on the file and follow instructions. A VirtualBox group will be created on the Start menu.

3. After starting VirtualBox, you would see a screen that shows the VirtualBox Environment with "Welcome to VirtualBox" message in it.
Refer the user manual http://download.virtualbox.org/virtualbox/4.3.28/UserManual.pdf if you run into any trouble.
Now that we have the VM program installed, we will need to get the Fedora operating system so you can add it as a host OS in the VM.

4. Installing Fedora 22 inside VirtualBox:a) Go to https://getfedora.org/en/workstation/download/ and download the ISO image of fedora 22 Workstation (Desktop) edition by clicking on “Download” button.b) Once you have the ISO image file, you are ready to install it on to the VM. Open your VM application if it is not already open. On the top of the window, click the “New” button.
c) This will open a virtual machine wizard for creating a new virtual machine. Fill in with the details as shown below and click “Next”.
Name : Fedora 22
Type : Linux
Version : Fedora (64 bit)
Memory size : 2048 (This can vary based on system configuration).
d) Select “Create a virtual hard drive now” and click on “Create”
e) Create a new Virtual Hard Drive as shown below and click on “Next”:
Hard drive file type : VDI
Storage on Physical HD : Fixed size
f) Select appropriate location for saving virtual disk image (VD), set the size of VD and click “Create”.
g) Once it is complete, you can see the screen with Fedora 22 listed.
5. 3) Now that the space for installing fedora 22 has been created, but there is still no Operating system associated with it. To install the downloaded fedora into this virtual space, select Fedora 22 in the left pane and click on “Start” button.
6. A wizard will be prompted to select the start-up disk. Browse to the Fedora 22 ISO image downloaded and click on “Start”.
7. After a while, you will see the screen with welcome window as shown below.
8. Click on “Install to Hard Drive” button to proceed.
9. Select Language as “English” and click “Continue”.
10. Click on “INSTALLATION DESTINATION” and select the 25GB hard drive that we just created.
11. Select the option of "Automatically Configure Partitioning" and click on “Done”.
12. Now click on “Begin Installation” button in the right bottom corner.
13. While the installation is in progress, create a root password and a new user by clicking on respective buttons.
14. And once the installation is completed, click on “Quit” button on the bottom right.
15. You should now see the fedora Home screen and be able to play around with the new interface of the Operating System.
